Like haircuts, eyebrow shapes aren’t a one-size-fits-all. It really depends on the dimensions of your face—and knowing how to shape them based on your specific face shape can not only emphasize your eye shape, but make you look good. The right brow will help open up the entire eye area and work to improve the face’s overall symmetry. The perfect brow will make you look overall more attractive.

Your unique face shape plays a role in determining which eyebrow shape works best for you. Here are some ideas for the best brows for a range of different face shapes.

For a square face: A square jaw accents the angularity of your face, so softly rounded brows are the way to go. Just make sure your brows are not too angular, but be aware of making brows appear too round; you don’t want to overpluck and create rainbow-shaped brows.

For a round face: If your face is round, you want to make sure your brows are very angular. Because there is a lack of definition in a rounder face, the perfect angled brow can bring out and define facial bone structure that is lacking or not present. In this case, a higher arch is flattering.

For a long face: A long face is characterized by features that are vertically stretched out. In this case, it is important to extend the tails of your brows east to west to really play up horizontal features. The tails of brows usually extend beyond the corner of the eye, but with a long face, you should make it a point for tails to extend a bit longer. It is important to be careful when sculpting the tail, however, as allowing it out too far will drag the eye down and make it appear droopy.

For a heart-shaped face: Although bold brows are in this season, a heart-shaped face should steer away from this trend. Because of the petite jawline and emphasis on the upper portion of the face, it is important to keep brows well-manicured and exceptionally groomed. That being said, a thin brow is never in. The idea here is to create a shape that is controlled and never bushy. This tight brow on the top hemisphere of the face will serve to balance the smaller chin and jawline of the bottom half.

For an oval face: A classic, balanced brow is perfect for this well-proportioned face shape.

For all face shapes: The head of the brow should begin at the bridge of your nose. This point can be easily found by vertically holding a pencil up to either side of your nose bone.

The arch of your eyebrows should be about two thirds of the way out. One of the biggest mistakes you can make is to create a centered arch that gives you the dreaded ‘rainbow’ shape.

Don’t cut your brows short. The tail should, at the very least, end on an imaginary line from the corner of the nose to the corner of the eye. You can allow it to extend slightly further as long as that tail doesn’t end lower than where the head begins (this can make the eyes look droopy). Make sure your tails always taper to a crisp point to best lift the eye.
